If you are using a Samsung handset and waiting for Android 6.0 Marshmallow, the wait might finally be over. A T-Mobile Galaxy Note 5 was spotted running Google's latest Android 6.0 Marshmallow in the U.S., hinting at an official rollout by Samsung soon. But Samsung is yet to complete its testing of Android 6.0 Marshmallow for its devices, which makes one wonder whether the rollout was a glitch.

The T-Mo user who received Marshmallow update on his Galaxy Note 5 was just as surprised and shared a screenshot of the device's About page on XDA Forums to get a better understanding. According to Android Origin, the updated Galaxy Note 5 had a broken IMEI, which means all telephony features were disabled on the Wi-Fi-only model and the latest software was downloaded from T-Mo's network.

The Android 6.0 Marshmallow rollout appeared to be an error and caused due to a bug in T-Mobile's network, the report adds.

The Samsung Galaxy Note 5 will be the first device in Samsung's lineup to get the latest update, which is expected by December, Phone Arena reported last week, citing a leaked update schedule by Samsung. There are other devices that will follow the lead, including Galaxy S6, Galaxy S6 Edge and Galaxy S6 Edge+ in January, the report added.

If Samsung begins the update process in December, which was the same time last year when the Lollipop started rolling out to users, carriers will push the software to a later date. T-Mobile, among other carriers, is expected to rollout Android Marshmallow to Galaxy Note 5 sometime in January or February.
